Morocco 2013 dates incorrect?
by Andrew Paprocki July 2, 2013

July 2, 2013

Currently I see these rules: Rule Morocco 2013 only - Jul 9 3:00 0 - Rule Morocco 2013 only - Aug 8 2:00 1:00 S I was just informed from the Casablanca Bourse that the exchange will return to standard time on July 7th and that Ramadan will start on July 9th or 10th. Are the current rules incorrectly assuming that return to standard time coincides with the start of Ramadan? Can anyone from Morocco confirm? Thanks, -Andrew

Time zone for Kosovo?
by Andy Heninger June 4, 2013

June 4, 2013

Are there plans to add a time zone for Kosovo? http://en.wikipedia.org/wiki/Republic_of_Kosovo An increasing number of organizations and countries are recognizing Kosovo as a country, and having a representative zone for it would be convenient. It looks like it would be Europe/Pristina, cloned from Europe/Belgrade Thanks, -- Andy

[PATCH] Adjust commentary to try to defuse recent issues somewhat.
by Paul Eggert May 30, 2013

May 30, 2013

This change stemmed from a long discussion on the tz mailing list about what country the Jerusalem zone entry is in. The idea of this change is to deemphasize the role of countries in the tz database, to lessen the amount of controversy in the future. Due to backward compatibility concerns this change does not eliminate the role of countries entirely. With one minor exception this change does not alter any code or data, just comments. * Theory, zone.tab: Deemphasize the role of countries in choosing location names, as they tend to introduce political conflict during maintenance, and country information isn't needed for typical uses of the database. * Theory: Say that names should differ in more than just case, and why; and explain why 'backward' means old names will continue to work. (thanks to Norbert Lindenberg for spotting these issues). Update citation date and URL. * iso3166.tab: Mention latest maintenance update. Update citation URL. Add missing comma for BQ. Be more consistent about abbreviating Sint like Saint. Mention SX "Dutch part" for consistency with MF "French part". * iso3166.tab, zone.tab: Add legal/territorial disclaimer. * zone.tab: Say that country/zone overlaps can occur in both directions, and that column 2 need not lie within column 1. (Asia/Jerusalem): Change the coordinates from a sloppy value, taken from an old astrology book, to a more-precise value, the site of city hall. The sloppy value sparked some controversy and the hope is that the more-precise value will be a bit less controversial. --- Theory | 27 ++++++++++++++------------- iso3166.tab | 21 ++++++++++----------- zone.tab | 17 ++++++++++++----- 3 files changed, 36 insertions(+), 29 deletions(-) diff --git a/Theory b/Theory index b00a492..751b12d 100644 --- a/Theory +++ b/Theory @@ -264,12 +264,12 @@ in decreasing order of importance: TZ strings.

problems with unsigned 32-bit time_t coming up
by Paul Eggert May 29, 2013

May 29, 2013

I vaguely recalled someone reporting trouble with the tz database on NetBSD or some other BSD in the past few months. The gist of it was that this platform has 32-bit 'long' and 64-bit 'time_t', and the tz code didn't play nicely on such a system. To try to catch this sort of thing I'd like to add support for trying different time_t types, even if they disagree with the system's time_t. I'll send a couple of proposed patches to the list to do that. I'll then follow up with a report of a bug in the reference implementation that is discovered by the patches, when configured to run with an unsigned 32-bit time_t. This isn't the NetBSD problem, but hey! at least there's an easy-to-run test case that illustrates the bug.
